Here's a simple lock mechanism, implemented via closure

const createLock = () => {

    let lockStatus = false

    const release = () => {
        lockStatus = false
    }

    const acuire = () => {
        if (lockStatus == true)
            return false
        lockStatus = true
        return true
    }
    
    return {
        lockStatus: lockStatus, 
        acuire: acuire,
        release: release,
    }
}

lock = createLock() // create a lock
lock.acuire() // acuired a lock

if (lock.acuire()){
  console.log("Was able to acuire");
} else {
  console.log("Was not to acuire"); // This will execute
}

lock.release() // now the lock is released

if(lock.acuire()){
  console.log("Was able to acuire"); // This will execute
} else {
  console.log("Was not to acuire"); 
}

lock.release() // Hey don't forget to release
